The wind turbines convert the wind's kinetic energy into electrical energy. The wind causes the turbine's blades to rotate. This movement is converted into electricity in the generator located in the engine house at the top of the towers. From there, the electricity is passed on to the electricity consumers.
Wind turbines begin to produce electricity at low wind speeds up to a maximum wind speed that is usually around 25 meters per second, which corresponds to full storm strength. There, the turbines are taken out of operation so as not to damage important equipment.
The wind increases with the height above the ground, therefore tall wind turbines are built to make optimal use of the wind.
Wind power in Sweden
The wind power expansion has progressed strongly in Sweden and today we are one of the countries in Europe that has the most wind power in relation to the total energy production in the country.
With a planned phase-out of nuclear power, wind power is expected to play an even greater role in the future energy system. Large land areas, good wind conditions and a stable, deregulated electricity market mean that Sweden has good conditions for establishing large-scale wind power.
